SFB CloudPBX Load/Stress Testing Made Easy

A Must Do task before and (even after) we deploy CloudPBX, What we, as well as customers should be fully aware of, is that how a customer’s network is performing under a duress and contentious concurrent Audio traffic load.

Also whether a customer’s network meets network performance requirement/benchmark recommended by Microsoft. So, two main critical objectives here:

1. To have full understanding and visibility on how a customer’s network is performing under a stress and contentious concurrent Audio traffic load.
2. To determine and pinpoint whether a customer’s network meets network performance requirement/benchmark set by Microsoft

The most critical aspect of SFB CloudPBX is practically Audio traffic while all other traffics such as Video, and Application sharing are just unifying features rather than fundamental or survival ones.

So, now we need to generate Audio traffic load from users’ network(s). The tool that I am going to use to do just that is Microsoft Network Assessment Tool

And I am largely following Skype for Business Operations Framework guidelines with my own automation and customization approach to fit in a common customer’s network environment.

Approach in running MNAT

• Download MNAT (Microsoft Network Assessment Tool) and extract it on users’ PCs – may be under C: drive as c:\mnat. You could use USB stick to copy and paste it on all users’ PCs or use a network share to copy and paste the extracted MNAT folder.
• MNAT use a command line to generate an audio traffic lasting 17 seconds (you can’t change 17 seconds call duration)
• MNAT should run on, if possible, all users’ PCs or at least on 10-to-20 PCs based on possible numbers of concurrent users – the point is that we need to generate 10-20 or your desired concurrent audio calls traffic using users’ PCs.
